- Boosts GMRS Performance: As a 1/4 wave monopole antenna, it is specifically tuned to maximize your signal range and clarity on 2M/70CM frequencies (Including GMRS), giving you a distinct advantage over standard equipment.
- Durable Construction: Built to withstand the harsh conditions of the backcountry, the Maximus can be bent, twisted, and abused and will still be ready when you need it.

I have three Maximus antennas and they are outstanding. Top notch quality and functionality, not to mention excellent customer service. Don't hesitate to get one. You will not be disappointed.
Excellent quality product!
Great antenna and greatly improved reception and reliability
I think this antenna makes a difference. I tested the SWR on my HT's and got about 2.3:1 which is fine for handhelds. I tested it over an undulating valley with a fellow ham radio operator and he literally said that my signal improved 10 times. I was ecstatic that this antenna made so much of a difference. Thank you guys for making a great product.
